http://struts.apache.org/1.2.7/api/org/apache/struts/action/DynaActionForm.h tml#initialize(org.apache.struts.action.ActionMapping) quote Since Struts 1.1, the reset method no longer initializes property values to those specified in <form-property> elements in the Struts module configuration file. If you wish to utilize that behavior, the simplest solution is to subclass DynaActionForm and call the initialize method inside it.
1)setup FormBeanConfig supplying name and type http://struts.apache.org/1.2.7/api/org/apache/struts/config/FormBeanConfig.h tml beanconfig.setName("name"); and then beanConfig.setType("org.apache.struts.action.DynaActionForm"); 2)// Construct a corresponding DynaActionFormClass http://struts.apache.org/1.2.7/api/org/apache/struts/action/DynaActionFormCl ass.html dynaClass = new DynaActionFormClass(beanConfig); constructing the DynaActionForm for FormBeanConfig class 3)2 ways to initialize DynaActionForm Initialize your DynaActionForm is with FormBeanConfig if you have a <form-bean> of struts-config file http://struts.apache.org/1.2.7/api/org/apache/struts/action/DynaActionForm.h tml#initialize(org.apache.struts.config.FormBeanConfig) the other initialize method assumes you are initializing properties from <form-property> of struts-config file http://struts.apache.org/1.2.7/api/org/apache/struts/action/ActionMapping.ht ml complete example located at /src/test/org/apache/struts/action/TestDynaActionFormClass.java M-- ----- Original Message ----- From: "Vinny" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <user@struts.apache.org> Sent: Friday, November 30, 2007 8:57 PM Subject: Re: zoning out on some basic LazyDynaMap usage for a text field property? > Hmm, > I've never tried using lazy inside a standard ActionForm, the ones that I > have work inside of > a DynaValidatorActionFom (say that 3 times fast).
